Answer:
Explanation:
Newton's law of gravitation states that every particle of matter attracts any other particle in the universe with a force directly proportional to the product of there masses and inversely proportional to the square of the distance between them.
This law is also called universal law because it is applicable to all masses at all distances irrespective of the medium.
False
Answer: The given statement is false.
Explanation:
In industries water is used for many purposes like washing, cooling, fabricating, diluting etc.
Therefore, huge amount of water is used by industries and also waste water or non-consumptive water is thrown by industries into rivers, sea, lakes etc.
An industry can avoid the unnecessary usage of water in various process so that water can be conserved as water is a precious resource of nature.
Therefore, the statement since 40 percent of industrial water use is non-consumptive, there is little that industry can do to conserve even more water, is false.
The answer isFALSE.
Not true
Latency heat is that heat which is either released or absorbed when a substance changes its physical state at constant temperature eg. from solid to liquid at the melting point or from liquid to gas at boiling point.
The change of phase always occurs with a change of heat. However the temperature does not change because that heat energy is used to overcome cohesive forces between molecules of that substance, no part of heat energy is used to increase the kinetic energy of the molecules. Similarly, heat energy is released and molecules of that substance comes closer but temperature doesn't decrease. So its temperature will not rise/decrease since the kinetic energy of molecules remains the same.

B. They cannot be divided into simpler substances
C. They break down when reacting with acids
D. They can be altered with and electric current
Answer:
B
Explanation:
They are the BASE elements. Cannot make them any simpler.
A bumper car with a mass of 200 kilograms traveling at a velocity of 3.5 meters/second collides with a stationary bumper car with a mass of 250 kilograms. the kinetic energy of the system after the collision is 1190,25 J.
The energy is the ability to work or produce action or movement and it manifests itself in many different ways mostly body movement, heat, electricity, etc.
The different types of energy are Kinetic energy is associated with the movement of bodies. Potential energy which is stored form of energy by virtue of a body's position relative to its surface is also called gravitational potential energy.
Thermal Energy associated with the kinetic energy of the molecules that make up an element, Chemical energy released from chemical reactions, Solar energy released from sunlight.
Ek = (m·V²)/2
V - velocity of system after the collision
m = m1 + m2
Ek = (m1 + m2)·V²/2
Ek = (200 +250)·2,3²/2 = 450·5,29/2 = 1190,25 J

The reason why the reaction takes place faster when the temperature is higher is that the collision of particles of the object increases. In order to have a faster reaction, you would need the particles of the object to get excited and increase its collision to other particles. This can be achieved through increasing the temperature.
Answer:
14,400 meters
Explanation:
yes
